Unfortunately the apartment wasn't what we expected. The biggest issues were the cleanliness and the comfort.
The apartment had simply not been cleaned, old food in the sink, hair and mold in the shower, toilet dirty, surfaces uncleaned. We sent photos and made a request to have it cleaned, but it took Airbnb getting involved before it was fixed the host basically told us "yes it is clean" even when we sent the photos of dirt, old food and mold. The least you would expect is the apartment to be clean, but it just wasn't.
The second issue was the comfort, for us, the apartment wasn't comfortable, the matrass is like a brick, just so hard that we struggled to sleep and the sofa is old and uncomfortable.
The internet is also unusable, it's there, but the fastest I ever got it was 0.5mbps. Sometimes you can use the building Wifi, but it would be good to have it in the apartment.
The location is a close to the BTS, but there is not much going on around the apartment, so if you want restaurants, cafes etc, possibly this isn't for you.
Lastly, it is not allowed to rent this out, so staying there feels very dodgy, you have to meet in the basement for checkin so the reception don't see you, you can't speak to the building staff and technically can't use the gym or pool, though you may get away with this. It's a bit uncomfortable to have to walk past a sign every day saying you can go to jail for staying there.
If you are staying for a week, get a hotel, if you are staying for longer, get somewhere better. Just don't stay here.
